View 3 RepliesI have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

I have created a application which checks if the text in clipboard starts with "file", and if it starts with the word file it process the clipboard text and then replaces it with < a href="some value">
For example it clipboard string file:///C:/Users/Searock/Desktop/dotnet/Apress.Pro.VB.2008.and.the.dot.NET.3.5.Platform.3rd.Edition.Mar.2008.html#link22

Has anybody done it successfully without having to resort to pre-printed checks.
I wanted to create a function that checks to see what button has been clicked on the windows form. For example If I had 10 generic buttons that open up different audio files. I would I create one Sub that can verify which button has been selected. I was either going to use a case statement or an if else. I did not want to create one sub for each button since it would be a lot of duplication in code.

First off, I'm using Visual Basic 2010. I've done pretty well with starting out with some basic things. Copying some codes from tutorials to learn what each code does. But lately I've been venturing into possibilities of ideas in my head, and the recent idea is very simple, but I'm not sure how to approach it.
I have a main form that has options to open up other forms. And in one of those other forms, I want to make it so that you can enter text into a textbox, then click a button to "save" the textbox's content so that anytime the program starts, that previously saved content of the textbox will be the same.
And on top of that, I want to relate the textbox back to the code in the main form.
If I didn't explain that well enough, I'm working on making an extremely basic web-browser (a big jump from what I've been doing), and I added the option under a menustrip to open up Form5 to change the home-page.
I want to make it so i click the button and text gets added to the textbox the current carat location and then the carat is placed at the end of the selected text.[code]...
How can i put the carat just after where the text was inserted after pressing a button?
I have a database created and tables inserted into it. One of the tables is called UserLogin. It consists of two columns, BarcodeId and Technician. I have a barcode value, and what I am trying to do is check if any of the values in the BarcodeId column of this table is equal to the barcode that I have. Then when I get a match, I want to get the Technician that matches that BarcodeId and display the Technician in a text box.
I was using this code sample:
Private Sub HasRows(ByVal connection As SqlCeConnection)

Dim command As SqlCeCommand = New SqlCeCommand( _

I want to check on the server for the existence of an image, then if it does exist, display the image wrapped in other code. E.g.
if "/images/name.jpg" exists then
<div><img src="/images/name.jpg"></div>

Do nothing.
Seems really simple to me but NOTHING I have tried has worked (compilation errors). I've tried examples using system.io, DIM stuff with 'FileInfo', Set fs. FileInfo examples produce 'not defined' errors, 'Set' says it's outdated and not used anymore and so on.
